Django - Return foreignkey field in string method

I want to return a foreign key field value as the unicode or string method of another model.. like this..

class Schedule(models.Model):
    month = models.charField(max_length=20)
    .... lots more fields here

    def __str__(self):
        return related_model.Event.long_name

class Event(models.Model):
    schedule = models.Foreignkey(Schedule)
    long_name = models.CharField(max_length=100)

I'm not sure how to do it, because if the order of the classes is reversed then Event can't have a foreign key to Schedule.

What would be the correct way to do this kind of thing?

My understanding is that an event can have multiple schedules, which might be possibly what you want. If that is the case, change your models to this 

class Event(models.Model):
    long_name = somefield


class Schedule(models.Model):
    event = models.ForeignKey(Event)

    def __str__(self):
        return self.event.long_name
